If you sell on eBay, you've probably had an email or a banner asking for your National Insurance number, and wondered what eBay is about to tell HMRC about you. This is the page that answers it properly.
Since 1 January 2024, the UK's digital platform reporting rules mean eBay (and every other online marketplace) has to collect details about active sellers and send them to HMRC once a year. This post explains exactly what data gets shared, the thresholds that trigger it, the dates it happens, and the part most articles skip: being reported is not the same as owing tax.
It's written for hobby sellers clearing out the loft, side-hustlers flipping stock, and full-time eBay businesses. Wherever you sit, you'll know where you stand by the end.
Does eBay report my sales to HMRC?
Yes. If your activity passes a low threshold in a calendar year, eBay is legally required to send your details and your sales figures to HMRC by the following January. It does this under the UK's digital platform reporting rules, which started on 1 January 2024.
These rules apply to all UK online marketplaces, not just eBay. They came from the OECD's model reporting rules and were brought into UK law through The Platform Operators (Due Diligence and Reporting Requirements) Regulations 2023. The aim is to give HMRC visibility of online income, not to create a new tax.
That last point matters, so we'll keep coming back to it: the rules change what HMRC can see, not what you owe.
What are the eBay reporting thresholds?
eBay reports a seller to HMRC if, in a single calendar year, you cross either of two thresholds. You only need to trip one of them.
| Threshold | Trigger point | Notes |
|---|---|---|
| Number of sales | 30 or more sales of goods | Counted across the calendar year (1 January to 31 December) |
| Total amount received | €2,000 or more | gov.uk gives the rough sterling figure as about £1,700 |
The gov.uk guidance frames the exemption the other way round: a seller who makes fewer than 30 sales of goods and receives less than €2,000 (about £1,700) in the year does not get reported. Cross either line and you're in scope.
Because the threshold is set in euros, the sterling equivalent moves with exchange rates. For its 2026 reporting cycle, eBay set the sterling figure at £1,707 (down from £1,740 the year before), reflecting HMRC's published exchange rate for converting the €2,000 limit. Treat the £1,700-ish figure as a guide and the 30-sales count as a hard line.
A quick word on what counts. The €2,000 figure is the consideration you receive as a seller, after eBay's own fees and commissions are deducted, not your profit. Thirty separate sales of cheap items can put you over the count threshold even if the money involved is small.
What data does eBay send to HMRC?
If you cross a threshold, eBay reports identifying information about you alongside your sales figures. For an individual seller, that means your full name, the address where you normally live, your date of birth, and your tax identification number, which for a UK resident is your National Insurance number.
That's why eBay asks you to add your National Insurance number to your account once you're in scope. If you don't provide it, eBay can restrict payouts until you do.
For a seller registered as a business entity, the reportable details are the legal business name, the main business address, and the tax identification number, which for a UK company is the company registration number.
Alongside your identity, eBay reports the financial picture for the year:
- The total amount paid or credited to you over the calendar year, broken down by quarter
- The number of sales transactions
- Any fees, commissions or taxes eBay withheld or charged
- The bank or payout account details the money was paid into
Crucially, eBay must give you a copy of the same information it sends to HMRC. Keep it. It's a tidy, ready-made summary of your year's activity, and it's the figure HMRC will already be holding when it looks at your record.
What dates does eBay report on, and when?
The reporting period is the calendar year, 1 January to 31 December, not the 6 April to 5 April UK tax year. That mismatch trips people up, so it's worth flagging early.
The platform then has to file the report with HMRC by 31 January following the end of that calendar year.
| Calendar year of sales | eBay reports to HMRC by | Your copy arrives |
|---|---|---|
| 1 Jan to 31 Dec 2024 | 31 January 2025 | January 2025 |
| 1 Jan to 31 Dec 2025 | 31 January 2026 | January 2026 |
| 1 Jan to 31 Dec 2026 | 31 January 2027 | January 2027 |
So your first ever report under these rules covered the 2024 calendar year and reached HMRC by 31 January 2025. Your 2025 activity was reported by 31 January 2026.
Remember the two calendars don't line up. Your eBay report runs January to December. Your Self Assessment return runs 6 April to 5 April. If HMRC ever queries a figure, expect to reconcile the two, which is far easier if you've kept your own monthly records rather than relying on eBay's calendar-year total alone.
Does being reported mean I owe tax?
No. HMRC has been explicit that there are no new tax rules here and that being reported does not automatically mean tax is due. If you're only selling your own unwanted possessions, it's very unlikely you'll owe anything.
The reporting threshold and the tax question are two completely separate tests:
- The reporting threshold (30 sales or about £1,700) decides whether eBay sends your data to HMRC.
- The tax question (are you trading, and is your trading income over the £1,000 trading allowance) decides whether you actually owe tax.
You can easily be reported without owing a penny, for example if you sell 35 items decluttering your house. You can also owe tax without being reported, for example if you run a small flipping side-hustle that happens to stay under 30 sales but makes a healthy profit. The data share is a visibility tool, not a tax demand.
This is the single most misread part of the whole regime, and the reason the £1,700 figure causes needless panic every January.
Selling personal items vs trading: which are you?
The line that actually decides tax is whether you're trading. HMRC treats you as trading if you buy goods to resell, or make goods, with the intention of selling them at a profit, or if you provide a service through a platform.
If you're trading, the £1,000 trading allowance for 2025/26 is your friend. If your gross trading income across all your trades is £1,000 or less in a tax year, you generally don't need to tell HMRC or file a return (unless another reason applies, such as wanting to pay voluntary Class 2 National Insurance). Go over £1,000 gross and you must register for Self Assessment by 5 October following the end of that tax year.
Above £1,000 you have a choice: deduct your actual allowable expenses, or claim the £1,000 trading allowance as a flat deduction instead, whichever leaves you better off. You can't do both.
Selling genuinely personal possessions is different again. That's not trading, so income tax doesn't apply to it. The only tax that could touch a one-off personal sale is Capital Gains Tax, and even then only where a single item (or set) sells for £6,000 or more. Everyday clear-outs of clothes, an old phone or used furniture fall well under that, so there's nothing to pay.
If you're building this into a proper business, our guide for eBay sellers walks through registration, bookkeeping and the VAT picture in more depth, and the wider ecommerce accounting hub covers multi-channel sellers.
Illustrative example: three eBay sellers compared
Illustrative example. Three made-up sellers, same calendar year, very different outcomes. Figures use the 2025/26 trading allowance of £1,000 and the CGT personal-possessions limit of £6,000.
Asha, decluttering. Asha sells 40 items from her wardrobe and loft for £900 total over the year. She crosses the 30-sales threshold, so eBay reports her to HMRC by 31 January following the year-end. But she's selling personal possessions, not trading, and no single item came close to £6,000. She owes no income tax and no CGT. The report is just data.
Ben, side-hustle flipper. Ben buys job lots of trainers and resells them, taking £4,200 in gross sales across 90 transactions. He's clearly trading and is over both reporting thresholds. His gross income is above £1,000, so he must register for Self Assessment by 5 October following the tax year. Say his allowable costs (stock, postage, eBay fees) are £2,600. He compares: deduct actual expenses (£4,200 minus £2,600 = £1,600 taxable profit) versus claiming the £1,000 trading allowance (£4,200 minus £1,000 = £3,200). Actual expenses win, so he reports a £1,600 profit.
Chloe, just over the allowance. Chloe makes and sells craft kits, taking £1,300 gross with very low costs. She's trading and over the £1,000 allowance, so she registers for Self Assessment. She claims the £1,000 trading allowance rather than itemising tiny expenses, leaving £300 of taxable profit (£1,300 minus £1,000). Whether any tax is actually due then depends on her other income and her Personal Allowance of £12,570 for 2025/26.
The pattern: the report is automatic once you cross a threshold, but the tax outcome depends entirely on whether you're trading and by how much you clear the allowance.
What should I do if eBay reports me?
Don't panic, and don't ignore it. Work through these steps.
- Add your National Insurance number when eBay asks. It's a legal requirement once you're in scope, and missing it can hold up your payouts.
- Download and keep your eBay report. It's your copy of exactly what HMRC receives. File it with your records.
- Decide honestly whether you're trading. Clearing out your own things is not trading. Buying or making to sell at a profit is.
- If you're trading and over £1,000 gross, register for Self Assessment by 5 October following the tax year and keep monthly income and expense records.
- If you're only selling personal items, keep a note of what you sold and why, in case HMRC's data prompts a routine letter. There's usually nothing to pay.
If you'd rather have someone confirm where you stand and handle the filing, that's exactly what we do. Talk to a Zmartly accountant about your eBay selling and we'll tell you plainly whether you owe anything and what to file. You can also let our Self Assessment service take the return off your plate entirely.
Frequently asked questions
At what point does eBay tell HMRC about my sales?
eBay reports you if, in a calendar year, you make 30 or more sales of goods or receive €2,000 or more (about £1,700, set by eBay at £1,707 for its 2026 cycle). Cross either threshold and your details go to HMRC by the following 31 January.
Does eBay reporting me mean I have to pay tax?
No. Reporting and tax are separate tests. HMRC has confirmed there are no new tax rules and that being reported does not automatically mean tax is due. You only owe income tax if you're trading and your gross income exceeds the £1,000 trading allowance for 2025/26.
What information does eBay send to HMRC?
For an individual, eBay reports your full name, home address, date of birth and National Insurance number, plus your total sales for the year (broken down by quarter), the number of transactions, fees charged and your payout account details. Businesses report their legal name, business address and company registration number instead.
What period does the eBay report cover?
The calendar year, 1 January to 31 December, not the 6 April to 5 April UK tax year. eBay must file with HMRC by 31 January after the year ends, so 2025 sales were reported by 31 January 2026.
I'm just selling my old clothes and clutter. Will I be taxed?
Almost certainly not. Selling your own personal possessions is not trading, so income tax doesn't apply. Capital Gains Tax only bites where a single item or set sells for £6,000 or more, which everyday clear-outs don't reach. You may still be reported if you cross 30 sales, but that's data, not a tax bill.
Do I need to register for Self Assessment if I sell on eBay?
Only if you're trading and your gross trading income is more than £1,000 in a tax year. If so, register by 5 October following the end of that tax year. If you're only selling personal items, or your trading income is £1,000 or less, you generally don't need to register.
